Abstract: 158,958. Baehr, G. Nov. 5, 1919. Die-rolling.-The housing of a die-rolling mill is constructed to permit the ready interchange of rolls of widely differing diameter, such as would be used respectively in rolling endless strings of long aeroplane braces or crow-bars or of short tools such as chisels, punches, spikes, &c. Each side frame 4, 5, Fig. 2, has a series of notches 9, Fig. 3, to accommodate blocks 21, one of which, shown in Fig. 3, serves as a cap for holding down the lower roll bearing on an integral bridge 20. The blocks can be. inserted in any pair of notches and serve as caps, or, by inverting them, as supports for springs 31 on which the bearing of the upper rolls are mounted. The pass-adjusting screws 32 work in yokes 6. Change-gearing 37, carried by slotted brackets bolted on the side frame 4, maintains the rolls in phase, lateral register being obtained by screws 28<a> in end plates bolted on the frames and retaining the bearings in place laterally. The die segments 14 are bevelled and retained in position on the rolls by clamping-rings 17.

Abstract: 388,841. Braking electric motors. HAMMOND, E. N., Oakley Lodge, Thetford Road, New Malden, Surrey. Oct. 2, 1931, No. 27431. [Class 103 (i).] For controlling the speed of an alternating- current motor driving a lift, crane or other device an eddy-current brake comprising a steel or like drum and a stator having a field winding is coupled thereto. As applied to lifts, the shaft c<1> of the motor c which is coupled to the usual worm gearing b of the lift drive, has mounted thereon the steel or like drum d<1> of the eddy-current brake, the field winding d<2> of which is carried by the carcase of the device- and is supplied through a rectifier r from the mains. The motor may thus be slowed down to a crawl speed by inserting the starting resistance g in the motor circuit and by supplying current to the winding d<2>. The brake may be controlled from the car or automatically by the pushbutton control method. The brake may be geared to the motor.

Abstract: 636,883. Arc-rupturing in switches. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 16, 1946, No. 27745. Convention date, Sept. 17, 1945. [Class 38 (v)] An arc shoot for a heavy-duty D.C. circuitbreaker such as disclosed in Specification 565,823 and having fixed and movable arcing contacts 3, 5, comprises high melting-point magnetic arc runners 12. 13 situated in two rear compartments formed by insulating plates 8, 9 and a shaped insulating barrier 30, and having lower portions 14, 15 extending into a front compartment formed by insulating plates 7, 8. The plate 8 has elongated openings 31, 32 extending from a base 33 of the barrier 30 and situated above and parallel to the arc runners. The arc runner 12 is mounted on a terminal 1, insulating fillers 16, 17 and a replaceabove slidable filler 18 being interposed between it and insulating end spacers 10, 11. The arc runner 13 is supported in insulating spacers 21, 22 between baffle plates 23 and has its upper end 28 bent through 90-180 degrees to cause movement of the arc root, thereby minimizing localized heating of the runner with consequent metallic vaporization. When the arc rises up the runners under the action of the magnetic flux, its ends pass through the openings 31, 32 into the rear compartments, leaving the main body in the front compartment separate from the metal-contaminated ends. To prevent reformation of the arc outside the shoot, the plate 8 is made larger than plates 7, 9.

Abstract: 948,590. Hydraulic dampers. LIONELPACIFIC Inc. July 19, 1962, No. 27762/62. Heading F2S. An hydraulic damper comprises a housing having a chamber 24 at least part of which is cylindrical, the chamber being closed at each end by members 46, 60 which are provided with bores coaxial with the chamber and forming a clearance fit for a shaft 20. The shaft 20 and the cylindrical chamber wall are provided with at least one longitudinal vane 80, 82, 84 and rib 26, 28, 30 respectively, which rib(s) extends between closure members 46, 60, there being a small clearance between the adjacent faces of the rib(s) and shaft and of the vane(s) and chamber wall. In the construction shown, six variable chambers (a), (b), (c), (d), (e) and (f) are formed in the housing. The shaft 20 is mounted at each end in bearings 53, 66 which are pre-loaded by members 58, 70 screwed into the housing. A temperature-sensitive metering device is housed in a bore 168 of shaft 20. The device includes a stack of bi-metallic thermostatic elements 182 mounted on a rod 180 which is adjustably positioned in the bore 168 by screw members 174, 176. The thermostatic elements at one end engage a washer 194 of a spring-loaded valve element 190, the position of which varies the metering effect between ports 212, 216 and a groove 200 of an axially tapered depression 198 in the valve element 190. Variable chambers (a), (c) and (e) communicate with groove 200 through ports 206, 208, 210 and ports 202, 203, 204 respectively and chambers (b), (d) and (f) communicate with bore 164 through ports 218, 220, 222 (not shown). Thus in operation fluid may pass from one set of variable chambers to the other set through the tapered depression 198. A reservoir housing 14 is formed integral with the shaft housing, the reservoir being provided with a spring- loaded piston 100 having a bore in which a fluid filling device 118, 122, 124 and a filtering device 116 are positioned. Pressurized fluid is fed into the two sets of variable chambers through commo n passage 130 and then through branch passages 136, 134 (not shown) and ball valves 144, 145 (not shown). Bleed chambers, passages and grooves for escaping fluid and gases which may have been entrained in the damping fluid are formed at each end of the shaft housing, these chambers, passages and grooves being vented through ducts 160, 162 into the fluid reservoir.

Filed: 1966-06-22
Abstract: 1,152,586. Gyroscopes. S.G. BROWN Ltd. D. BARNETT and N.J. MYALL. June 21, 1967 [June 22, 1966], No.27801/66. Heading G1C. A gyroscope comprises a gyro rotor 26 mounted in a casing 28 by means permitting angular displacement of the rotor spin axis from a drive axis 20 about which torque to spin the rotor is applied and means for influencing the angular position of the rotor spin axis comprising permanent magnets 34, 36 carried by the casing and magnetizable means e.g. an annular magnetic armature 30 carried by the rotor. The permanent magnets can be fixed on the casing in such a position that the magnetic forces act through the centre of suspension of the rotor when the rotor spin axis coincides with the drive axis so as to only influence the angular position of the rotor spin axis when this axis is angularly displaced from the drive axis. Alternatively the permanent magnets may be movably mounted on the casing e.g. a pair of short arcuate permanent magnets mounted on a carrier pivotable about an axis at right angles to the drive axis 20 and passing through the centre of suspension. The carrier can be moved e.g. electrically from a neutral position in which no torque is applied to the rotor to an effective position in which a known torque is applied about the magnets pivotal axis. In the embodiment described the carrier may be moved by means of an induction motor secured to the wall of the casing, the carrier having a strip armature. The rotor assembly is as described in Specification 1,148,582.

Title: Improvements in the production of acetic acid
Inventor: THOMAS EDWARD BOADEN
IPC: C07C51/12
Filed: 1949-11-04
Abstract: Acetic acid is made continuously be reacting carbon monoxide and methanol in a reaction zone at a pressure of less than 50 atmospheres and at a temperature below 250 DEG  C. which is sufficiently elevated to prevent condensation of the acetic acid produced, in presence of active carbon impregnated with nickel iodide, iodine lost from the active carbon being replaced during the process.  Methyl iodide recovered from the effluent may be introduced with the reactants to replace iodine lost, and nickel carbonyl to replace nickel lost, or instead of continuously replenishing the nickel the carbon may be intermittently treated with nickel iodide solution.  Water vapour may be present during the reaction.  The product obtained by reacting carbon monoxide and hydrogen in presence of a methanol-forming catalyst may be used directly without separating the methanol.  Any catalytically-active material in the effluent may be removed therefrom by passing the effluent through active carbon maintained at a lower temperature.  Examples are given.

Title: Improvements in or relating to self-lapping driver's brake valve devices
IPC: B60T15/04
Filed: 1935-10-14
Abstract: 446,158. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., 82, York Road, King's Cross, London.- (Assignees of Lynn, E. K. ; 1372, Broadway, East McKeesport, Pennsylvania, U.S.A.) Oct. 14, 1935, No. 28338. Convention date, Jan. 11. [Class 103 (i)] [See also Group XXIX] A self-lapping driver's valve comprising a spring 20 and a piston acted on by brake cylinder pressure to return the valve to lap position comprises a further piston which balances the effort of the first piston so that opening of the supply valve is not opposed by this effort. A chamber 10 is connected to the brake cylinder 11, to which fluid is supplied and from which fluid is released by inlet valve 26 and exhaust valve 33 respectively, controlled by opposed pistons 16, 17 both subject to the pressure in the chamber 10 and engaging one another by means of a spring 20. The driver's handle 52 by means of a cam 50 is adapted to seat the valve 33 against the piston 16 which moves the spring 20 and piston 17 to open the inlet valve 26 by means of a projection 31 against a spring 28. Pressure fluid is thus admitted from the reservoir 24 to the chamber 10 and the brake cylinder 11 and forces the piston 17 to the left to allow the valve 26 to reclose to give lap position, the supply valve spring 28 being stronger than the release valve spring 36 and the spring 20 stronger than both these springs. Reverse movement of handle 52 for release opens the valve 33, exhausting the brake cylinder and the chamber 10 by means of a passage 44. Fall of pressure in the chamber 10 causes the piston 16 to move to the left and reclose on the valve 33 to give a lap position.
